论文摘要
驱动开放系统的量子动力学应与量子机械和热力学原理兼容。通过根据一组假定的形式制定热力学原理，我们获得了热力学一致的主方程。遵循公理方法，我们将分析基于自主描述，将驱动器作为大型瞬态控制量子系统结合起来。在适当的物理极限中，我们得出了半古典描述，其中控制在哈密顿式系统中作为时间依赖性项并入。向半古典描述的过渡反映了整体连贯性的保护，并突出了连贯性在初始控制状态中的关键作用。我们通过在连贯状态下通过单个骨值控制的量子量进行分析来证明理论。
Quantum dynamics of driven open systems should be compatible with both quantum mechanic and thermodynamic principles. By formulating the thermodynamic principles in terms of a set of postulates we obtain a thermodynamically consistent master equation. Following an axiomatic approach, we base the analysis on an autonomous description, incorporating the drive as a large transient control quantum system. In the appropriate physical limit, we derive the semi-classical description, where the control is incorporated as a time-dependent term in the system Hamiltonian. The transition to the semi-classical description reflects the conservation of global coherence and highlights the crucial role of coherence in the initial control state. We demonstrate the theory by analyzing a qubit controlled by a single bosonic mode in a coherent state.
